(Received 9 March, 2001; accepted 10 December, 2001) Abstract On-farm experiments were conducted in Chinyika Resettlement Area during the 1994/95 and 1995/96 rainy seasons at four sites to test the effectiveness of intercropping maize with cowpea, groundnut, field bean and bambara nut in suppressing Striga asiatica (L.) Kuntze. During the 1994/95 rainy season maize/cowpea intercrop supported less S. asiatica plant m-2 than sole maize, while other intercrops supported similar numbers of emerged S. asiatica plants m-2 as sole maize. Combined analysis over sites showed that the numbers of emerged S. asiatica plants in the intercrops were similar to those in sole maize during the 1995/96 season. However, during the same season the number of emerged S. asiatica plants was significantly (P
